A piston combustion bowl (20) for a diesel engine is described. The piston (10) may decrease the production of particulate matter during combustion of the fuel vapour in the combustion chamber (11). The piston (10) may comprise a body (12) having a crown (14) about a central axis (P); a combustion chamber (11) transversely disposed in the body (12) and recessed from the crown (14); a centre pip (22) disposed in the combustion chamber (11) about the central axis (P); a bowl (20) extending from the centre pip (22) to a lip (18) inclined relative to the crown (14) at an angle; and a wall (16) connected between the lip (18) and the crown (14) for limiting angular distribution of fuel vapour exiting the combustion chamber (11). |
